Application of High Pressure Jet Grouting in Gravel Formation

Abstract:

The high pressure jet grouting method has advantages of wide application, easy construction, simple equipment and convenient management, which has been widely applied in foundation seepage control for hydraulic structure. According to the high pressure jet grouting construction in tailrace of Lingguan hydropower station, the paper introduced the problems encountered in the construction and the treatment measures to provide reference for the similar engineering.

Key words:high pressure grouting; single-row rotary jetting pile overlapping; quality control; seepage control effect
